EARTH DISTINCTION CONTROL DEVICE OF 154KV,345KV TRANSMISSION LINE

摘要

The present invention relates to a device for discriminating and controlling the grounding of 154kv and 345kv transmission lines. To determine and control the grounding of transmission lines, when a signal is input through CVT, amplify and filter the digital data through the A / D converter. The data is calculated every cycle, and there is no voltage at grounding and the ground voltage is determined by the algorithm related to the induced voltage of the transmission line. Device.
